Two EVGA GeForce GTX 780 Ti Dual Classified's too overkill?

I'm coming up with different scenarios right for my gaming PC I'm going to be building soon. I'm a man that would like to save money to get this thing faster. Don't be surprised if you see my post 20 times a day asking for advice, because I'm still kind of a new builder, and I want to get everything right the first time, as I'm a huge perfectionist. :-\ Anyways, here's the build that I was originally going with... The budget was no more than $3600...

Now, I wanted a computer that...
- Was very overclockable. I was going to overclock this thing very high, and very often.
- Silent, or close to it
- FUTURE PROOF. Most of the games I'm going to be playing the most aren't releasing until later in the year, and since I'm building a computer that is almost half a year sooner than these games, I wanted to build graphical power that can run the games like The Division, Star Citizen, Dragon Age: Inquisition, and more, on Ultra on 1440p, which is the main reason I went with 2-way SLI.
- Lot's of Storage
- Water-cooled
- 2 Monitors. I already have one monitor I can use, and the monitor in the build would be my main gaming monitor, as the one I have now would be my side monitor.


Now, here's the changes I was thinking of. First, I would swap out one of the 780 Ti's, and put another one of the PB287Q monitors, so I can have dual 1440p monitors, and I can ditch the 1080p one I have now. i'm scared to remove one of the graphics cards though, as I'm afraid that 6 months down the road, when The Division, and Star Citizen release, the card would be outdated, and I wouldn't be able to run it at Max settings. I'm a huge graphics freak, so I want the best possible graphics and FPS when I'm playing. Secondly, if I did downgrade to one GPU, I was probably going to lower my PSU, to maybe a Corsair 860i. Now, the Case fans are planned out, so I know what fans I want. So, my main point is, can I sacrifice a GPU for a 1440p monitor, and still be able to play the games I will play the most on Ultra 1440p? If you can come up with any other substitutions that I should consider, that would be great.
